mPEG-Biotin (Biotin-PEG) is a biotinylation reagent that consists of a PEG chain linked to a biotin molecule. mPEG-Biotin is widely used for the biotinylation of biomolecules and surface modification. The biotin group enables sensitive detection through biotin–streptavidin binding assays and is commonly used for molecular target recognition. The PEG chain improves stability and reduces non-specific adsorption, enhancing detection accuracy. In addition, mPEG-Biotin is frequently used for nanoparticle and surface modification, where it minimizes protein adsorption while providing controllable functional sites. It can also participate in self-assembly systems to form well-defined multicomponent structures. In separation and purification, it serves as a capture tag in biotin–streptavidin systems, enabling highly selective isolation with improved efficiency and reduced background binding.
